CAP AND RING SPINNING AND LIKE FRAME.

Application filed February 1. 1926, .No.

Our invention refers to cap and ring,

spinning and like framesand has forits object improvements in mechanism for effecting dofiing allied operations. I

According to the invention there is provided for carrying the bobbins in spinning position a set of bobbin-carriers each rotatable upon a horizontal axis in front of or behind the line of spinning whereby full bobbins may be moved from spinning position and empty bobbins moved into spinning position. Axles on which the carriers are mounted to rotate are bored axially for passage of a rod or member for operating. yarn severing devices after dofiing or for elfect- Cap tubes or ring spindles carrying the bob-bins are mounted upon the carriers, each tube or. spindle in spinning position being driven by a tape wrappinga wharve on the under side of the carrier, the wharve being thus overhung to permit downward shift of the tape from the wharve on to a temporary holder, such as a loose pulley, during dotiing The tape is shifted from the wharve to the loose pulley preferably by reversing the driving cylinder which ensures the unwinding of sutiicient yarn from'the spinning bobbin to prevent breakage in dotting.

lVhen a set of bobbins is filled, by turning the carrier the full bobbins are moved away from spinning position and empty bobbins moved into spinning position. I Then the threads extending from the full bobbins are given one or more turns around the empty bobbins, and are cut and spinning is resumed. In the accompanying drawing, Fig. 1 1s a diagrammatic part elevation part section showing part of a spinning frame according to the invention; Figs. 2 to 7 are detail views, Figs 2 and 3 showing a traverse poker 8, Fig. 4 a notched rotary disc, Fig. 5 axles on which carriers are mounted and 6 and 7 yarn severing devices.

Referring to the drawings, 1 denotes a' horizontally disposer top rail extending along the rear side of the frame. In front of the top rail 1 is a thread board 2 with guides such as 3 through which the threads 4 to be spun pass from the drawing roller. Vertically below each guide 3 is mounted a cap spindle 5 at the upper end of which is a cap 6. The lower end 5 of the cap spindle 5 is fixed in a cap spindle rail 7 disposed 85,814, and in Great Britain February 7, 1925.

horizontally parallel with the top rail 1, and at a suitable distance below the board 2. At a suitable distance in front of and below the caps 6 is mounted in bearings aset of traverse pokers 8 suitably spaced apart andhaving at their upper ends bearings v disposed horizontally parallel with the top rail 1. The pokers 8 are adapted to be traversed up and down by ordinary traverse In the bearings 9 are fitted mechanism. axles 10 with axial bores 10 On the axles 10 between adjacent pokers 8'is mounted a rotatable bobbin carrier 11' which acts as a lifting rail to traverse the spinning bob-.

side of the bobbin carrier .11 is ino'uited' coaxial with the cap spindle 5 a cap tube 13 preterably clear of the cap spindle 5.

The cap tube 13 is mounted in abearing 14 in the bobbin carrier 11 and extends upwards to a suitable height. Just clear of the bearing 14; is mounted onthe cap tube 13 a disc 15 with feathers 15 on its upper side to drive the spinning bobbin 12. On the periphery of the disc 15 is formed a notch 15 to catch and wind theyarn from the doffed bobbin around the cap tube, as hereafter explained.

the cap tube 1.8 is driven by a tape 16 in usual manner. On the cap spindle 5 below the wharve 13 is mounted a loose pulley 17 supported on the cap spindle rail 7. On the front and'under side of the carrier 11 at the same distance from the axles 10 as the tube 13 is mounted a cap tube 18 (similar to the tube 13) with its wharve 13 on top. On this cap tube 13 is mounted an empty spinning bobbin 1%. hen the spinning bobbin 12 in spinning position is full, the frame is'stopped, the cap 6 is gripped at its upper end by the forked lever 6 hinged on the top rail 1, the driving cylinder not shown, is reversed by hand and the tape 16 shifted from the wharve 13 On theunder side. of the disc 15 a groovel5 1S iormed to receive of the working cap tube 13 on to the loose pulley 17. The cap spindle 5 and the rail 7 with the loose pulley 17 and tape 16 are then lowered by rotation of a shaft 18 carrying a pulley 18 wrapped by a chain 19 to make room for the bobbin carrier 11 to perform a semi-rotation, whereby the full bobbin 12 and cap tube 13 are carried to the position until now occupied by the empty bobbin 12 and its cap tube 13 which by the same movement are carried into spinning position. As the cylinder is reversed to ship the tape 16 on to the loose pulley 17, the full spinning bobbin 12 is also rotated backwards and suliicient yarn is unwound to permit the full bobbin to be carried to dofiing position. The cap spindle 5 and rail 7 with the loose pulley 17 are then raised and the cap 6 seated on its spindle 5, and its holder removed. The cylinder is then turned by hand in the usual direction to cause the tape 16 to rise from the loose pulley 17 on to the wharve 13 As the wharve 13 and therewith the cap tube 13 are rotated the disc 15 is caused to catch the thread extending from the guide 3 to the full bobbin to wind it around the cap tube 13 which is now ready to resume spinning. On the rail 7 is mounted at a suitable height and in suitable position a rod 20 extending along the under side of the bobbin carrier 11. The rod 20 guides the yarn from the full bobbin across the path of one of two yarn cutters by which the yarn is severed prior to the restarting of the frame. Each yarn cutter comprises a horizontal plunger 21 mounted on the bobbin carrier 11 and sliding in a half tube 23. The half tube is formed with a gap and the plunger has a notch 24- into which the yarn is guided at dofling by the rod 20. Through the bores 10 in the axles 10 extends a rod 25 from which a cross pin 26 enters each plunger 21. \Vhen the rod 2-5 is moved endways, the relative plunger 21 severs the thread at each spindle.

What we claim is 1. In a cap or ring spinning frame or the like a carrier rotatable on a horizontal axis and presenting bearings on opposite sides of said axis, core-elements rotatable in said bearings, and a driving wharve connected to each core-element and movable therewith and with its bearing from spinning to do'lfing position.

2. In a cap or ring spinning frame or the like, a carrier, horizontal axle members on which said carrier is rotatably mounted, said members having axial bores, said carrier presenting bearings on opposite sides of said axle members, core elements rotatable in said bearings, a driving wharve connected to each core-element and movable therewith and with its bearing from spinning to doifing position, and means passing through the bores of said axles and movable toeffect a dofling operation.

3. In a cap or ring spinning frameor the like, driven bobbins, bearings for said bobbins, overhung wharves connected to said bobbins and movable with said bobbins and their bearings from spinning to dotling position, and means supported by the frame separately from and below said wharves to receive a transmission element when shifted from a wharve for dofling. V

1. In a cap or ring spinning or like frame, in combination, a bobbin carrier rotatable on a horizontal axis and presenting bearings, bobbins sustained by said bearings, bobbin driving wharves movable with said bobbins and their bearings from spinning to dofiing position on rotation of said carrier, and means for driving the wharves in V spinning position but disengageable from said wharves when said wharves are moved from spinning to dofing position.

5. In a cap or ring spinning or like frame, in combination, a movable bobbin carrier presenting bearings, bobbins sustained by said bearings, bobbin driving wharves shift able with said bobbins and their bearings from spinning to dofling position, and means for driving the wharve in spinning position, said means adapted to be reversed to cause thread to be unwound from a full bobbin before shifting from spinning position to doffing position.

6. In a cap or ring spinning frame or the like, a bearing member, a spindle, a tube surrounding said spindle and rotatable in a bearing in said member, an overhung tape-driven wharve connected to said tube and movable with said tube and its bearing from spinning to dotting position, and a separate tape-receiving member below said wharve to receive the tape during dofiing.

In testimony whereof we have signed our names to this specification.
